6 Claims.

This invention relates to means. for forming a relatively small pocket or compartment on either the front or back of a relatively large envelope, or on the outer surface of a box or carton, or on a package, or on any sort of container that can be transmitted through the mails.

Generally stated, the object of the invention is to provide a novel and improved construction and arrangement whereby the said pocket or relatively small compartment is formed by a single sheet of paper having single thickness edges that are pasted to the outer surface of the relatively large envelope or other container, so that said sheet forms only the outer wall of the pocket or relatively small compartment, in combination with means on the back or inner surface of said sheet for fastening a letter or other first-class mail matter in place thereon, thereby forming a so-called pastor or label that can be attached, to the letter or other first-class mail matter, and thereafter secured to the relatively large envelope or other container, with provisions for an address on the front of said sheet, so that the entire envelope or container structure thus formed, with relatively large and small compartments, is adapted to pass through the mails as a. single piece of mail matter, notwithstanding that the larger compartment for mail matter less than first-class may be left open for inspection of the contents thereof.

, It. is also an object to provide certain details and features of construction tending to increase the general efficiency and desirability of means of this particular character for forming a duplex envelope or other mailing container.

To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawing, in which- Fig. 1 is a perspective showing a duplex envelope embodying the principles of. the invention.

Fig..2'is an enlarged horizontal section on line 2-2 in Fig. 1 of the drawing.

Fig. 3 is a perspective showing the rear of a single sheet of paper from which the relatively small compartment is formed on the outside of the relatively large envelope shown in Fig. 1 of the drawing.

Fig. 4 is a similar view showing a folded letter or other mail matter secured to the inner surface of said sheet of paper.

Fig. 5 is a view similar to Fig. 3, showing a somewhat different form of the invention.

As thus illustrated, referring to Figs. 1 to l, inclusive, the invention comprises a single sheet of paper I, having its inner surf-ace gummed at 2 along the margin thereof. The said sheet is formed with cut-out flaps 3 that are also gummed on their inner surfaces. The sheet may be provided, if desired, with the ordinary transparent window t to display the address on the letter or other contents of the relatively small pocket thus formed on the outer surface of the relatively large envelope 5, when the gum 2 on the said sheet is moistened and pasted to the outer surface of the relatively large envelope.

In use, the folded letter 6, or other piece of first-class mail matter, can be laid on the inner surface of the sheet I, as shown in Fig. 4 of the drawing, and the gum on the flaps 3 can be moistened to make them adhere to the said letter or other article, as indicated in Fig. 4 of the drawing. Thus, the letter or other piece of mail matter can be fastened to the sheet I, before the latter is attached to the relatively large envelope, and thus a one-thickness paster is formed that can nevertheless be loaded with a letter or other piece of mail matter, before the paster or so-called label is attached to the relatively large envelope. The flaps 3, when pushed out, form holes I, through which an instrument, or even a finger, can be inserted to tear 01f the pastor or label when the duplex envelope thus formed is received by the person to whom it was addressed.

In Fig. 5, the construction is substantially the same as that previously described, except that in this case the gum strips 8 are made wider than they are shown in Figs. 3 and 4 of the drawing, so that they include the flaps 3, and in this way the sheet will adhere to the large envelope more closely along the edges of the letter or other piece of mail matter carried in the pocket or relatively small compartment thus formed, and in this case all the gummed surface would be moistened at the same time, whereas in Figs. 1 and 2 the gum on the flaps Swould be moistened to adhere to the letter or other piece of mail matter, but the gum 2 could remain unmoistened for some time afterward, or until the label or paster, and perhaps several hundred more like it, were carried in a basket or other means to a place where these single sheet address labels were applied to the relatively large envelopes or other containers; but with the form of the invention shown in Fig. 5, the letter or other piece of mail matter could be immediately attached to the sheet or address label, and with all the gummed surface moistened, the label could be immediately applied to the relatively large envelope or other mailing container. In other words, in Figs. 3 and 4, there could be two successive moistening operations, with any desired degree of time between, whereas in Fig. there would naturally be only one moistening operation, because the label would then be practically immediately applied to the envelope or other contain-er.

Thus, the paster or the address label is provided, which comprises only a single sheet of paper and which has only a front wall of the pocket or smaller compartment, but which can be loaded with a letter or other piece of mail matter and then, any time thereafter, attached to a relatively large envelope or other mailing container, whereby a considerable saving in paper is effected, inasmuch as the outer wall of the larger compartment is made to serve also as the inner wall of the smaller compartment.

What I claim as my invention is:

1. A paster or label comprising only a single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, to form a pocket with only a single wall formed by said sheet, forming the outer wall of the pocket, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, with said attaching means interposed between the container and said mail matter, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps cut out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter.

2. A paster or label comprising only a single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, to form a pocket with only a; single wall formed by said sheet, forming the outer wall of the pocket, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, with said attaching means interposed between the container and said mail matter, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps cut out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter, the attachment of said flaps to the letter or other piece of mail matter leaving the sheet with openings through which an instrument may be inserted to rip the sheet to obtain the contents of the pocket thus formed by the sheet.

,3. A paster or label comprising only a single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, to form a pocket with only a single wall formed by said sheet, forming the outer wall of the pocket, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, with said attaching means interposed between the container and said mail matter, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps cut out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter, said flaps forming circumscribed holes between the oppo site edges of the letter or other piece of mail matter and the end edges of the said paster sheet.

4. A paster or label-like single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps cut out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter. 7

5. A paster or label-like single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps cut out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter, the attachment of said flaps to the letter or other piece of mail matter leaving the sheet with openings through which an instrument may be inserted to rip the sheet to obtain the contents of the pocket thus formed by the sheet.

6. A paster or label-like single sheet of paper to be pasted on the outer surface of a relatively large envelope or other mailing container or package, having means for attaching a letter or invoice or other piece of mail matter to the inner surface thereof, so that the two will not become separated, and having some single thickness edge portions for thereafter adhesively attaching the so-called label or paster to the outer surface of the relatively large envelope or other mailing container, said means for attaching the letter or other piece of mail matter in place on the inner surface of the label sheet comprising flaps out out from the end portions of the sheet and gummed on their inner surfaces, so that they may be pushed inwardly and around the edges of the letter or other piece of mail matter, and then made to adhere to the latter, said flaps forming circumscribed holes between the opposite edges of the letter or other piece of mail matter and the end edges of the said paster sheet.
